Unique, externally adjustable, and wear compensating, this screwed bonnet-type needle valve offers a long and trouble-free service life in most liquid or gas applications.

Designed with a free-floating O-ring for improved tolerance to particular contaminations, this high-flow, zero-leak, low-pressure check valve is suitable for fluid and gas applications. With metal-to-metal positive stops in both the open and checked position, this valve protects the O-ring and spring from over-stress fatigue.

Designed with an integral bonnet, this forged needle valve features a PTFE and metallic wafer stem packing, which provides long-life and leak-tight service from vacuum to the maximum operating pressure.

With a metal-to-metal positive stop, this direct-acting inline check valve ensures a long service life and is suitable for pressure and vacuum applications. Bubble tight sealing is achieved by a line of contact between a seat and a standard elastomer O-ring with minimum differential pressure, regardless of mounting attitude.

Compact with a fully retained O-ring seal, this one-piece check valve is poppet type and suitable for working pressures to 3000 psig. Also, this valve is 100% factory tested and available cleaned and packaged for oxygen service.
